Instead of checking both env->features and ena_mask at two different places in the CPUID code, initialize ena_mask based on the features that are enabled for the CPU, and then clear unsupported bits based on kvm_arch_get_supported_cpuid().

2016-09-27target-i386: Don't try to enable PT State xsave componentEduardo Habkost
The code that calculates the set of supported XSAVE components on CPUID looks at ext_save_areas to find out which components should be enabled. However, if there are zeroed entries in the ext_save_areas array, the ((env->features[esa->feature] & esa->bits) == esa->bits) check will always succeed and QEMU will unconditionally try to enable the component. Luckily this never caused any problems because the only missing entry in ext_save_areas is the PT State component (bit 8), and KVM currently doesn't support it (so it was cleared on ena_mask). But the code was still incorrect and would break if KVM starts returning CPUID[EAX=0xD,ECX=0].EAX[bit 8] as supported on GET_SUPPORTED_CPUID. Fix the problem by changing the code to not enable a XSAVE component if ExtSaveArea::bits is zero.

This was already done for CPUID[7].EBX, and is now made generic for all CPUID feature flags.

2016-09-27filter-rewriter: rewrite tcp packet to keep secondary connectionZhang Chen
We will rewrite tcp packet secondary received and sent. When colo guest is a tcp server. Firstly, client start a tcp handshake. the packet's seq=client_seq, ack=0,flag=SYN. COLO primary guest get this pkt and mirror(filter-mirror) to secondary guest, secondary get it use filter-redirector. Then,primary guest response pkt (seq=primary_seq,ack=client_seq+1,flag=ACK|SYN). secondary guest response pkt (seq=secondary_seq,ack=client_seq+1,flag=ACK|SYN). In here,we use filter-rewriter save the secondary_seq to it's tcp connection. Finally handshake,client send pkt (seq=client_seq+1,ack=primary_seq+1,flag=ACK). Here,filter-rewriter can get primary_seq, and rewrite ack from primary_seq+1 to secondary_seq+1, recalculate checksum. So the secondary tcp connection kept good. When we send/recv packet. client send pkt(seq=client_seq+1+data_len,ack=primary_seq+1,flag=ACK|PSH). filter-rewriter rewrite ack and send to secondary guest. primary guest response pkt (seq=primary_seq+1,ack=client_seq+1+data_len,flag=ACK) secondary guest response pkt (seq=secondary_seq+1,ack=client_seq+1+data_len,flag=ACK) we rewrite secondary guest seq from secondary_seq+1 to primary_seq+1. So tcp connection kept good. In code We use offset( = secondary_seq - primary_seq ) to rewrite seq or ack. handle_primary_tcp_pkt: tcp_pkt->th_ack += offset; handle_secondary_tcp_pkt: tcp_pkt->th_seq -= offset; Signed-off-by: Zhang Chen <zhangchen.fnst@cn.fujitsu.com> Signed-off-by: Li Zhijian <lizhijian@cn.fujitsu.com> Signed-off-by: Wen Congyang <wency@cn.fujitsu.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

In this patch we use kernel jhash table to track connection, and then enqueue net packet like this: + CompareState ++ | | +---------------+ +---------------+ +---------------+ |conn list +--->conn +--------->conn | +---------------+ +---------------+ +---------------+ | | | | | | +---------------+ +---v----+ +---v----+ +---v----+ +---v----+ |primary | |secondary |primary | |secondary |packet | |packet + |packet | |packet + +--------+ +--------+ +--------+ +--------+ | | | | +---v----+ +---v----+ +---v----+ +---v----+ |primary | |secondary |primary | |secondary |packet | |packet + |packet | |packet + +--------+ +--------+ +--------+ +--------+ | | | | +---v----+ +---v----+ +---v----+ +---v----+ |primary | |secondary |primary | |secondary |packet | |packet + |packet | |packet + +--------+ +--------+ +--------+ +--------+ We use conn_list to record connection info. When we want to enqueue a packet, firstly get the connection from connection_track_table. then push the packet to g_queue(pri/sec) in it's own conn.
